SHUTTER ACTUAT ING MECHANISM 1 Filed Feb. 20, 1957 2 Sheets-Sheet 2 Patented Aug. 9, 1938 SHUTTER ACTUATING MECHANISM August Nagel, Stuttgart, Germany, assignor to Eastman Kodak Company, Rochester, N. Y., a corporation of New Jersey Application February 20, 1937, Serial No. 126,896 In Germany October 1, 1936 12 Claims.

This invention relates to photography, and more particularly to a folding camera wherein the shutter which is of the setting type is set and released by means of a common actuating member which is mounted on a camera body.

One object of my invention is to provide a folding camera which is equipped with a shutter of the setting type with an actuating mechanism by means of which the shutter can be set and released in proper sequence by means of a single actuating member.

Another object is to provide a shutter actuating mechanism of the type referred to wherein the actuating member therefore is mounted on the camera body.

And still another object is to provide a shutter actuating mechanism of the type referred to which is so constructed that no disconnection of its several parts is required when the camera is collapsed.

Briefly, my invention comprises a rod which is so mounted in the camera body parallel to the axle of the camera bed as to be longitudinally displaceable therein. This rod is adapted to operate two driver members which cooperatep-ositively with a pair of motion transmitting means, one of which actuates a driver ring on the shutter for cocking or setting the same, while the other actuates the shutter trigger after the shutter has been set.

The novel features that I consider characteristic of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and its methods of operation, together with additional objects and advantages thereof, will best be understood from the following description of specific embodiments when read in connection with thhe accompanying drawings in which,

Fig. 1 is a plan View of a folding camera with certain parts thereof removed, and showing my novel shutter actuating mechanism in its inoperative position.

Fig. 2 is a longitudinal section taken on line AA of Fig. 1, the shutter being omitted for the sake of clarity.

Fig. 3 is a plan view corresponding to Fig. 1 after a setting of the shutter has been effected,

Fig. 4 is a plan view corresponding to Fig. 1 after the release of the shutter has been effected, and

Fig. 5 is a partial front elevation corresponding to Fig. 1, with the camera body and all parts mounted therein being omitted for the purpose of clarity.

Like reference characters refer to corresponding parts throughout the drawings.

Referring now to the drawings, rod 6 is slidably mounted in the camera body I and is carried in the side wall 2 and the bearing 3 parallel to the bearings 4 of the camera bed 5. Rod 6 carries; a finger 8 fixed at its inner end i, and finger 8 has an oblique part H at its end H] which faces the shutter 8. The oblique part I! is formed by bevelling the end of the finger 8 in both plan View and side elevation, as clearly indicated in the drawings, so that it can slide over the end l5 of the arm It in one direction for the purpose hereinafter described. The shutter 9 can be foldably mounted on the camera bed 5 and be connected to the camera body I by means of a bellows in any customary manner, not shown, so that it will collapse to allow the bed 5 to fold into the camera body to close the same when the camera is not being used. A lever i3 is rotatably pivoted to the bed 5 by screw it, and the end [5 of an arm Id of the lever bears against the longitudinal edge 52 of the finger 8. The other arm I? of the lever 93 has, on itsfront end if), an extension 19 which is bent off vertically to the camera bed 5. Bearing against this extension is an arm 2! and a ring 20 which is rotatably mounted about the casing of the shutter 9, and this ring possesses a forked projection 22 which embraces the lever 23 serving to set the shutter. A helical spring 24, one end of which is fastened to the arm I l and has its other end arranged in any suitable manner on the camera bed, tends to normally hold the lever l4 against the stop pin 25 which is fixed to the camera bed 5.

A helical spring 25 is fastened at one end to the finger 8 and at the other end to the bearing 21 so that it normally pulls the finger 8 toward the bearing 3 which serves as a stop therefor.

The bearing 21 carries the pin' 28 which is directed parallel to the bearings 4 of the bed 5 and parallel to the rod 6. This pin 28 serves as a longitudinal securing means for the slide 25. Slide 29 has extensions 3!] and 3| which are directed vertically upward. An extension. 32 slidably mounted on the rod 5 grasps the extension 3! in a fork-like manner, and has a longitudinal slot 33 in which a cross pin 34 on rod 5 engages and has its abutment at the end 35 of slot 33. Between the extension 32 and the bearing 3 there is located a helical spring 35 by means of which a slide 29 is pressed with its extension 30 against the bearing 21.

Cooperating with slide 29 by means of a pin 38 and a slot 39 is a lever 31 which is rotatably the slot 33.

mounted to the bed 5 by screw 40. The other end 4| of the lever 31 has a vertical projection 43 which faces and is in the path of the shutter trigger 42 when the camera is moved to its open position, as shown in Fig. l.

The method of operation of this device is as follows: When the user of the camera presses against the button 44 with his hand, the rod 5 is displaced transversely of the camera body I and finger 8 thereon is moved along with it. This finger presses, with its edge l2, against the end I5 of the lever l3, and rocks the latter about its pivot l6. The end IQ of the lever l3 presses against the arm 2| on the ring 20 and rotates it around the casing of the shutter 9. When this is being done, the yoke 22 takes the setting lever 23 with it, and thus sets the shutter, see Fig. 3. At the same time, the lever I3 is released from the part 8 and swings back into its original position, the rocking movement thereof being limited by the pin 25.

The pin 34 on the rod 6 then takes the part 32 with it on its further displacement, since this pin bears with pressure against the end of The part 32, which embraces the projection 3| on the slide 29 in a fork-like manner, moves the slide 29 along the pin 28 and consequently causes the lever 31 to rock about its pivot 40. The end 43 of the lever 31 presses aonagainst the shutter trigger 42 to effect a tripping of the same.

After the exposure of the film has been eifected in this way. the button 44 is released. The helical springs 36 and 2B compel the rod 6 and the , parts 8 and 32 to return to their initial positions, see Fig; 1. When this is being done, the finger 8, slides by virtue of its oblique part I I, over the end l5 of the lever I3, and is then rocked by the leaf spring 45 toward the camera bed 5, so that ;it again occupies the driving position in respect to the lever l3.

From the above description it will be understood that my apparatus provides for the setting and releasing of a camera shutter through the manual operation of but a single actuating memher, the actuation of both of said parts being effected by means of one directional movement of the actuating member which is mounted on the camera body of a folding camera remotely from the shutter. The present apparatus insures the cocking of a setting type shutter prior to the attempted release thereof, and thereby saves many an exposure which might be lost if a person attempted to release a setting type shutter before it was set. This novel shutter setting and releasing structure is simple and so inter-connected that it is automatically brought into operative position relative to the shutter when the camera is open for taking pictures.

Although I have shown and described certain specific embodiments of my invention, I am fully aware that many modifications thereof are possible. My invention, therefore, is not to be restricted except in so far as is necessitated by the prior art and by the spirit of the appended claims.
